FLUSHING-RIM SLOP-SINK.

SPECIFICATION forming part of Letters Patent N 0. 533,062, dated January29, 1895.

Application filed Eeptember 4, 1894| Serial No. 522,029- (No model.)

To all whom it may concern.-

Be it known that I, HERMAN M. HOELSCHER, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois,haveinvented a new and usefulIm provement in Flushing-Rim Slop-Sinks, ofwhich the following is a specification.

My invention relates to improvements in slop sinks which are furnishedwith flushing rims.

The object of my invention is to provide a flushing rim slop sink of asimple and durable construction, wherein the flushing rim is made in aseparate piece of metal from the sink itself and which may be readilyand conveniently secured thereto by a water tight joint by means ofscrews or bolts, while at the same time the flushing rim itself remainsimperforate and without screws or screw holes appearing on its uppersurface to form alodgment for dirt and render such'upper surfaceunsmooth and difficult to keep clean.

To this end my invention consists in the novel construction of parts andnovel combinations of parts and devices herein shown and described andmore particularly pointed out in the claims.

In the accompanying drawings which form a part of this specification,and in which similar letters of reference indicate like parts,

Figure l is a perspective view of a flushing slop sink embodying myinvention- Fig. 2 is a detail plan view of the sink with the Hushing rimremoved. Fig. 3 is a detail plan view of the rim inverted or turnedover. Fig. 4 is an enlarged detailvertical sectional view.

In the drawings A represents the slop sink, the same being preferably ofcast iron furnished. with a horizontal flange or rim 0;.

B is the flushing rim, the same being made preferablyof brass or othersuitable metal.

The flushing rim B is provided with a series of hollow internallythreaded projections 12, and the rim a is furnished with correspondingholes or openings a to receive the same.

C is a packing inserted between the rim a of the sinkAand the flushingrim B to insure a Water tight joint between the two.

The flushing rim and sink are securely clamped together to form a watertight joint between them by means of threaded bolts or screws D, theheads (1 of which bear against the washer 01 inserted between the rim 0,and said head cl. As the bolts D do not project through the flushing rimB, the upper surface of the flushing rim is left smooth and imperforate,while at the same time the flushing rim and sink are securely and firmlyattached together.

The hollow space or flushing chamber B between the flushing rim B andthe upper edge or rim or portion of the sink A is connected to orcommunicates with the water supply pipe in the usual manner; and b isthe opening or crevice for the discharge of the water at the lower edgeof the rim B between the lower edge 'of said rim and the wall of thesink A, as is clearly indicated in Fig. 4..

I claim 1. The combination with a sink having a perforated rim or flangeat its upper edge, of an imperforate flushing'rim having projections onits under side fitting in the perforations of the rim of the sink, andmeans for securing the rim and sink together, there being a hollow spaceor flushing chamber connected with the water supply between saidflushing rim and sink and a discharge opening for the water at the loweredge of said rim substantially as specified.

2. The combination of slop sink A with the imperfora-te flushing rim Bhaving hollow interiorly threaded integral projections fitting in holesin the rim of the sink, and threaded bolts D for securing the sink andflushing rim together, substantially as specified.

3. The combination with sink A having rim 61. provided with holes orperforations a, of the imperforate flushing rim D provided with threadedintegral projections b on its under face, packing C, screws D and washerd, all combined and cooperating, substantially as specified.
